Definitions
- the present invention relates to a herbicidal composition. More particularly, it relates to a herbicidal composition comprising as the essential active ingredient (a) 4-(4-chloro-2-fluoro-5-isopropoxyphenyl)-1,2-tetra- methyleneurazol (hereinafter referred to as "Compound (I)”) of the formula: and (b) at least one of ⁇ , ⁇ , ⁇ -trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (hereinafter referred to as "trifluralin”), 3-(3,4-dichlorophenyl)-1,1-dimethylurea (hereinafter referred to as “diuron”) and 1,1-dimethyl-3-(3-trifluoromethylphenyl)urea (hereinafter referred to as "fluometuron”), which exerts a highly enhanced herbicidal activity against various weeds, particularly Graminaceous weeds, without any material phyto
- Compound (I) is known to exert a herbicidal activity against various weeds, particularly broad-leaved weeds and Graminaceous weeds (cf. EP-A-0075267).
- its herbicidal activity against Graminaceous weeds is sometimes not sufficient when applied in small doses or at low concentrations.
- its application in a large doses or athigh concentrations may in a sufficient herbicidal activity against Graminaceous weeds, a phytotoxicity to cotton may simultaneously develop.
- composition according to the invention can exterminate or control a variety of weeds belonging to cotyledonous and dicotyledonous weeds, of which typical examples are as follows: common lambsquarters (Chenopodium album), redroot pigweed (Amaranthus retroflexus), smartweed (Polygonum sp.), chickweed (Stellaria media), common purslane (Pprtulaca oleracea), cocklebur (Xanthium strumarium), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), tall morningglory (Ipomoea purpurea), hemp sesbania (Sesbania exaltata) prickly sida (Sida spinosa), black nightshade (Solanum nigrum), green foxtail (Setaria viridis), large crabgrass (Digitaria sanguinalis), annual bluegrass (Poa annua), goosegrass (Eleusine indica), barnyard
- the composition of the invention may contain from 1 to 95 % by weight, preferably from 5 to 80 % by weight of the active ingredients, i.e. the components (a) and (b).
- the weight proportion of the components (a) and (b) in the composition may vary within a broad range, usually from 1 : 0.5 to 1 : 30.
- the weight proportion of the components (a) and (b) is normally 1 : 1 - 30.
- the component (b) is diuron and/or fluometuron, the normal weight proportion is 1 : 1 - 30.
- the composition may additionally contain a solid or liquid carrier or diluent. Any surface active or auxiliary agent may also be contained therein.
- the composition may be formulated in any conventional preparation form such as emulsifiable concentrate, wettable powder, suspension or granules.
- solid carrier or diluent there may be used kaolin clay, attapulgite clay, bentonite, terra alba, pyrophyllite, talc, diatomaceous earth, calcite, wallnut- shell powder, urea, ammonium sulfate, synthetic hydrated silicon dioxide, etc.
- liquid carrier or diluent are aromatic hydrocarbons (e.g. xylene, methylnaphthalene), alcohols (e.g. isopropanol, methylene glycol, cellosolve), Stones (e.g. acetone, cyclohexanone, isophorone), vegetable oils (e.g. soybean oil, cotton-seed oil), dimethylsulfoxide, acetonitrile, water, etc.
- the surface active agent used for emulsification, dispersion or spreading may be any of the anionic and nonionic type of agents.
- the surface active agent include alkylsulfates, alkylarylsulfonates, dialkylsulfosuccinates, phosphates of polyoxyethylenealkylaryl ethers, polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene polyoxypropylene block copolymers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, etc.
- the auxiliary agents include ligninsulfonates, sodium alginate, polyvinyl alcohol, gum arabic, CMC (carboxymethyl cellulose), PAP (isopropyl acid phosphate), etc.
- compositions according to the invention are illustratively shown in the following Formulation Examples wherein part(s) are by weight.
- Compound (I) 9 parts of fluometuron., 14 parts of polyoxyethylene styrylphenyl ether, 6 parts of calcium dodecylbenzenesulfonate and 70 parts of xylene are well mixed while being powdered to obtain an emulsifiable concentrate.
- Compound (I) Four parts of Compound (I), 21 parts of trifluralin, 3 parts of polyoxyethylene sorbitan monooleate, 3 parts of CMC and 69 parts of water are well mixed and pulverized until the particle size becomes less than 5 microns to obtain a suspension.
- Compound (I) Three parts of Compound (I), 22 parts of fluometuron, 3 parts of polyoxyethylene sorbitan monooleate, 3 . parts of CMC and 69 parts of water are well mixed and pulverized until the particle size becomes less than 5 microns to obtain a suspension.
- the composition thus prepared may be applied as such to the weeds. Alternatively, it may be applied by diluting with water. The application is effected, by such a means as foliar or soil treatment and, in case of the latter, the composition is sprayed to the soil surface, if necessary, followed by mixing up with the soil, or perfused into the soil.
- the herbicidal composition of the invention may be also used with other herbicides. Besides, it may be used in combination with insecticides, acaricides, nematocides, fungicides, plant growth regulators, fertilizers, soil improvers, etc.
- the dosage of the active ingredients may vary depending on prevailing weather conditions, soil involved, preparation form used, mixing proportion of each active ingredient, crop and weed species, etc. In general, however, the total amount of Compound (I) and trifluralin is favored to be within a range of 2.5 to 25 grams per are, preferably 3.5 to 16 grams, and the total amount of Compound (I) and diuron and/or fluometuron is favored to be within a range of 5.5 to 40 grams per are, preferably 7 to 28 grams.
- composition being formulated into an emulsifiable concentrate, wettable powder or suspension, it may be diluted with water and applied over the top at a volume of 1 to 10 liters per are to the foliage of the crop plants or weeds which germinate or have germinated.
- the dilution may include, in addition to the above mentioned surface active agent, any spreading or auxiliary agent such as polyoxyethylene resin acid esters, ligninsulfonates, abietic acid, dinaphthylmethanedisulfonates, paraffin and the like.
- the composition being formulated into granules is generally applied as such.
- the seeds of tall morningglory were sowed in a cylindrical pot (diameter, 10 cm; length, 10 cm) filled with field soil and covered therewith.
- a designed amount of the composition in the form of an emulsifiable concentrate powder formulated in accordance with Formulation Example 3 was diluted with water and sprayed to the soil surface at a spray volume of 10 liters per are by the aid of a small hand sprayer, followed by mixing up of the soil to the depth of 3 cm. After 20 days' cultivation in a greenhouse, the growth controlling percentage was observed. The results are shown in Table 1.
- the seeds of johnsongrass were sowed in a cylindrical pot (diameter, 10 cm; length, 10 cm) filled with field soil and covered therewith.
- a designed amount of the composition in the form of an emulsifiable concentrate powder formulated in accordance with Formulation Example 4 was diluted with water and sprayed to the soil surface at a spray volume of 10 liters per are by the aid of a small hand sprayer. After 20 days' cultivation in a greenhouse, the growth controlling percentage was observed. The results are shown in Table 2.
